Description

Funny, because 'svn log -rBASE:HEAD' works fine.

Look at libsvn_client/diff.c:do_diff().  It attempts to pigeonhole the
inputs into one of three scenarios:  wc vs. wc,  wc vs. repos, or
repos vs. repos.

The bug is that it's failing to recognize that a comparison between
BASE and HEAD falls into the 3rd category.   It's treating the BASE
concept as if it were a working-copy thing, when it *should* interpret
the keyword as a file's working revnum...(i.e. the revnum that the
text-base represents.)  Then it would have two specific server-side
revnums to compare.
